These bands can be used for strength and flexibility. Have you ever seen crossfit where they use bands to add resistance or aid in chin ups? Well these are the big elastic bands that they use. They come in different strengths, lengths and widths. They are great to adding resistance to your squats, chest press or lateral walks. Put them around your ankles and they immediately help you activate your glutes. I recommend these for any athlete, trainer or fitness enthusiast to add to their training tool kit.
